\VILLIAM VAN BUSKIRK, OF MILFORD, NEYV YORK.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 375,661, dated December 27, 1867.

Application filed April 19, 1887.

To aZZ whom it may concern.-

Be it known that 1, WILLIAM HENRY VAN BUSKIRK, a citizen of the United States, residing at Milford,in the county of Otsego and State of New York, have invented certain new and useful Improvements in Gar-Couplers, and I do declare the following to be a full, c1ear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

Figure 1 of the drawings is a plan view, partly in section; Fig. 2, a vertical median longitudinal section; Fig. 3, a side elevation of the draw-bar; Fig. 4, a detail plan view of the block which is fast to the under jaw.

In the drawings, A represents the draw-head, and B the draw-bar arranged therein so as to be readily removed therefrom, the two being held together against the draft by the couplingpin 0, which passes through the holes a b.

D is the pin'lever fulcrumed at d in earsf f on the upper jaw of coupling.

G is a plate pivoted in the front end of a rod, H, and slotted at g to receive and work over the fulcrum d,while its upper end passes through the lever-slot d, and is perforated at the top to receive a chain,l,which passes over a groove on the cam-lever J. The bar or rod H is slotted, as well as both jaws F F, to receive the rod K, which is pivoted to the tail end of lever, as well as in the bottom jaw, while it carries a spiral spring, L, between the upper jaw and the bar H. The latter has a right-angled rear arm, 71, which is pivoted in the upper jaw, F. The jaws F F are connected by the parallel plates M M ,end pivoted in each jaw.

N is a longitudinal rod which is pivoted in the rear end of the bar H, passes between theplates M M, and is pivoted to a plate, 0, endpivoted to the lower jaw, F, passing through the upper jaw, F, and provided with a rear stud, o.

P is a spring made fast at one end to the up- Scrial No. 935,411. (No modehl per jaw and supported .on the lower jaw to hold the pin out of the holef Q is a rest or block made fast to the bottom jaw andsupporting the top one when the cars are coupled. In this block is a hole, q, having the jaw F for half its bottom, the other half being an extension hole, q, through which the spring P passes when it is pushed back by the pressure of the end of the link against the slide-pin It, which has one head in the hole q and the other in front of the block Q,while its body passes through a horizontal slot in said block.

The operation is as follows: Suppose thejaw F and pin 0 are held'up, as shown in Fig. 2 of the drawings, then the link of draw-head in another car comes against the slide-pin R and forces the spring P, which holds thejaws apart,over the hole q',when the upper jaw,F', drops, the pin couples with the link, and the two cars are fastened together. In order to uncouple, the cam-lever J is raised from a horizontal to a vertical position. This lifts the slotted plate G, which lifts the bar H, with spiral spring L and upperjaw, as well as the pin mechanism, turns rearwardly (on its bottom pivot) the rod K, and pulls the plate 0 so as to bring the stud 0 within the slot of upper jaw. As soon as raised the vertical spring I? pushes forward the slide-pin R and is supported on the-bottom jaw. \Vhen thejaws are together with only the block Q between them and the coupling-pin in its place, the rear end of the top jaw is supported on the stud 0.

S is a buffer consisting of the headed pin 8 and the spiral spring 8, which bears against the framing T,slotted at t,to receive the headless end of the pin.

U is a link pivoted to the end of the pin 5, and to one end of a bent lever, V, fulcrumed to the framing T. This lever is connected by a pivoted rod, W, with the arm as of a shaft, X, having the hand-crank arm a.

The draw-head A has two side trunnions, a a, by which it is pivoted under the car, while by turning the crank-arm to the front of the draw-bar B may be raised or lowered to suit the elevation of the draw-bar on the car with which it is desired to couple.

Having thus decribed all that is necessary to a full understanding of my invention, what I jaw, the spiral spring L, rod N, and plate 0,

having stud 0, said stud supporting the rear end of said upper jaw when the cars are coupled, as set forth.

3. The combinati0n,with the two separable jaws F F, of the stiff vertical spring 1?, fast to the upper jaw, and the block Q, fast to lower jaw, said spring being arranged to support the 2 upper jaw and to pass through the block and I lower jaw, as described.

4:. The combination, with the jaws F F, block Q, and spring P, of the slide-pin R, arranged to be operated by the link, as and for the purpose specified.

5. The combination of the draw-head A, pivoted at the middle on each side of the buffer S, framing T, mechanism U V W, and shaft X, having arms a: m,to raise or lower the front end of draw-head,as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM HENRY VAN BUSKIRK.
